Other objects and advantages will be 'apcover Bbetween the binder-board 5 and facing parent to persons skilled in theart after my insheet 6 as shown in Fig. 3.

vention is understood from the within disclosure. The other binder stripD is spaced above the 55 binder strip just described and is in the formof a lateral flange projecting from the adjacent upper portion of thesupplementary or false back In order to face this false back I employ asmall piece of facing material and adhere it to the inner surface of theback member C to provide a decorative facing 8a thereon and I extend anedge portion 1a upon the inner surface of the cover A and adhere it tothe surface of the binder-board beneath the adjacent edge of the facingmaterial 6 as shown at the left in Fig. 3. The remaining portion of thepiece of facing material extends from the back 0 to the upper binderstrip D where it provides a facing l2 for the piece of thin binder-boardma forming a part of the upper binder strip. This decorative materialalso extends across a portion of the under surface of the binder-boardIlla as shown in detail in Fig. 3.

It will be noted the portion of the decorative material between thebinder strips D and E is close to or at the hinged edge of the lowerbinder strip E, and in order to secure the parts together, as well as toreinforce the false back I, a piece of strong fabric I3 is adhered tothe inside face of the decorative material and has its marginal portionsl3a and l3b adhered to the facing portions of the respective upper andlower binding strips D, E. This strong fabric strip or web 53 thusprovides the body portion of the supplementary or false back section Ithat is covered on its outer surface with the decorative facing materialand assists in connecting the binder strips D and E together in theirspaced relation.

The margins of the back C are reduced in thickness as at I4 to provideflexibility for hinging action between the covers and the back. Thefalse back I also has hinging action with respect to the back C and theadjacent cover B. The binder strips D, E likewise have hinging action atthe points l5 and I6, Fig. 3.

From the foregoing it will be book or portfolio presents the appearanceas an ordinary book or portfolio, but when the cover A is opened, asshown in the drawing, the leaves remain flat, and the back C will lieflat upon a table, desk or other support while the stack seen the closedThe decorative material beside providing the inner facing of the backmember C, and an outer facing for the false back I, enhances theappearance of the structure when the cover A has been opened. Thereinforcing fabric IS on the false back I will not readily be visiblenor will the portions No or I 3b of this material be visible becauseleaves held against the binder strips will prevent these portions beingseen.

What I claim is:

1. A device of the kind described comprising a back section, coversflexibly connected to the longitudinal edges of said back section, asupplementary back section flexibly connected to the before-mentionedstructure at substantially the juncture of one of the covers and thefirst-named back section, binder strips extending laterally fromopposite edges of said supplementary back section, and a strip ofmaterial extending continuously upon and secured to surfaces of both ofsaid back sections and constituting portions thereof, said strip ofmaterial also extended upon the binder strip projecting from the freeedge of the supplementary back section.

2. A binder comprising a back section, covers flexibly connectedthereto, a supplementary back section extending from said first-namedback section and disposed between said covers, a binder strip extendinglaterally from the free edge of said supplementary back section, asecond binder strip co-acting with said first-named binder strip andmounted adjacent the anchored edge of said supplementary back section,and a strip of material secured to and extending continuously across theadjacent surfaces of the said back sections and constituting portionsthereof.

3. A binder consisting of inner and outer bodies, each body comprisingtwo spaced members and an intermediate member that are hingedlyconnected along adjacent longitudinal edges, means connecting a hingeedge of the inner body to an adjacent hinge edge of the outer body, anda sheet of material disposed upon the inside face of the intermediatemember of the outer body, the outside face of the intermediate member ofthe inner body, and also across and concealing the line of connectionbetween said bodies, whereby to adapt one body for hinging movement withrespect to the other body, said material providing a finish on theintermediate member of the inner body that is exposed when the outerbody is opened.

4. A binder comprising a back section, covers flexibly connected toadjacent edges thereof, binder members one of which is disposed with amargin adjacent the juncture between a cover and said back section, andmeans connecting said binder members consisting of a body Web secured toopposing faces of said binder members for maintaining them in spacedrelation, and facing material secured upon the inner face of said backsection and extending across said body web and secured to a face of oneof said spaced binder members, whereby another back section is providedindependent of the firstmentioned back section, said other back sectionconnecting said binder members.
